“In the year 1620 there were planted upon this continent two ideas irreconcilably hostile to each other. Ideas are the great warriors of the world; and a war that has no ideas behind it is simply brutality. The two ideas were landed, one at Plymouth Rock from the _Mayflower_, and the other from a Dutch brig at Jamestown, Virginia. One was the old doctrine of Luther, that private judgment in politics as well as religion, is the right and duty of every man; and the other that capital should own labor, that the negro had no rights of manhood, and the white man might justly buy, own, and sell him and his offspring forever. Thus freedom and equality on the one hand, and on the other the slavery of one race and the domination of another, were the two germs planted on this continent. In our vast expanse of wilderness, for a long time, there was room for both; and their advocates began the race across the continent, each developing the social and political institutions of their choice. Both had vast interests in common; and for a long time neither was conscious of the fatal antagonisms that were developing. “For nearly two centuries there was no serious collision; but when the continent began to fill up, and the people began to jostle against each other; when the Roundhead and the Cavalier came near enough to measure opinions, the irreconcilable character of the two doctrines began to appear. Many conscientious men studied the subject, and came to the belief that slavery was a crime, a sin, or as Wesley said, ‘the sum of all villainies.’ This belief dwelt in small minorities for a long time. It lived in the churches and vestries, but later found its way into the civil and political organizations of the country, and finally found its way into this chamber. A few brave, clear-sighted, far-seeing men announced it here, a little more than a generation ago. A predecessor of mine, Joshua R. Giddings, following the lead of John Quincy Adams, of Massachusetts, almost alone held up the banner on this floor, and from year to year comrades came to his side. Through evil and through good report he pressed the question upon the conscience of the nation.
